To all whom it may concern: I V leaving an open space 2, Fig. 2, in the upper Be it known that I, CHRISTIAN WAIS, a portion 1, cut out at a right-angle, and when citizen of the United States of America, and the clutch 21, through its lever 10 is adjust a resident of Cincinnati, in the county of' ed Hamilton and State of Ohio, have invented shear 3 will descend at an angle of fortycertain new and useful Improvements in five degrees and operate upon the desired Shearing-Machines, of which the following metal to crosscut in any degree to forty-five is a specification. degrees through the aid, of the regulating dey invention relates to improvements in vice as shown in Fig. 4. This regulator is shearing-machines for use in cutting metalfastened on the side of the machine where he plates, bars, angles of even and uneven the metal is inserted, and is provided with a legs and channel-irons in any degree up to suitable scale or Vernier to determine the'deforty-five degrees, either jointly or sepasired degree of cutting, rately.- I attain these objects by means of arm 17 and a movable the machine or mechanism illustrated in the accompanying drawings in Wl11Cll igure 1 is a side view of my machine showing the two sets of cutting devices. Fig. 2 is another, but reversed, side view parallel to the side view shown in Fig. 1 with part of the frame cut out or removed, showing the combination of gearing. Fig. 3 is a vertical section through dotted-line a, b, "of Fig. 2, showing the fastening of the shaft to the frame. Fig. 4 isan enlarged view of theregulating device for determining the, degree of an les desired for cutting. Fig. 5 is also an en arged sectional plan view of the regulating device showingan angle-iron inpin 15 sliding verti- To allow pin 15 to keep sition and established degree upon the metal to be out, a set-screw 18, seen in Fig. 5, is provided in the outer end of the arm 17 and tightened till said pin 15 remains rigid. Through the above stated arrangement of shears, bars can be cut on eithershear, and extra shears for channel-irons can be inserted on either side, and the device can also be made to act as a punch .with, but few changes.

The friction-roller 19, Figs. 2 and 3, is provided on the outer corner of the upper porthe frame-opening therefor and'the regulattion 1, immediately in rear of the plate-shear ing device in operativeposition; opening, to divert and carry the sheared- ,Similar figures refer to similar parts strips downward and, also, to avoid fricthroughout the several views.

he upper portion 1, which. is composed of a single integral web and the lower standends 2 constitute the framework of the maportion 1 through suitable openin s at its two sides serves as hearing means for the plate-shear shaft 3 and angleshear shaft 4 and the attached gearing apparatus as shown in the vertical section, Fig. 3. Both said shafts are bedded in the a ertures of the upper portion 1, and plates ear 5 and angle-shear 3 Fig. 2, receive their operative power through pulley '6 and a transmitter or pinion 8, which latter, in turn, transmits power to the plate-shear and angle-shear gears 9 and 7 respectively, and the joint or se arate action of the machine is determined liy engaging or releasing the two clutch-levers 10 and 11. These'clutchlevers 1'0 and 11 swivel in a horizontal direction by'being bedded on a shoulder 12, Fig. which view (Fig. 3) the lever 10 is swung in line with shaft 3. The angle-shearing is accomplished by tional resistance against the bottom of framemember 1 when said strip is a wide one.

The gear-wheel 9 is provided witha hub 9 turning in a bearing 20, which is constructed in the gear-cover 20, as shown in the vertical section, Fig.

The laterally-extended hub 9 of the gearwheel 9 has a bearing in the laterally-extended hub 20 of the web or gear-cover 20 and the plate-shear shaft 3 bears in the said gear-wheel hub 9 thus dispensing with the use of brackets.

The angle-shear shaft 4 has a like bearing in the companion web part or armed member 4 (seen to the right in Fig. 2).

I claim 1. In a shearing machine, a frame formed of a lower part, an upper part composed of a single integral web bolted to said lower part, a plate-shear shaft and an angle-shear shaft shaft disposed adjacent to one another, a common transmitter in engagement with each gear, a clutch on each shaft, means for for action on the sheaves 14, the anglehaving an extended end of said arm 17 extended through said web, a gear on each i opening, a opening and embodying a pivoted. arm sehaving an opening and a knife operating of a lower part and an upper operating each clutch, and means carried by said web to support saidshafts, transmitter and clutches- 2. In a shearing machine, a frame embodying a lower part and an upper part composed of a single integral web bolted to said lower part, a pair of spaced hubs carried by said webs with openings formed in the web alinin g with the openings in the hubs, a plate shear shaft extending through one of said hubs and web openings, an angleshear shaft extending through the other hub and the other web opening, a gear on each shaft disposed adjacent said hubs, hubs on the gears having clutch faces, a common transmitter in engagement with each gear, a clutch. movable on each shaft at. the outer free ends thereof so as to engage and be disengaged from the clutch faces of said gears, and means carried by said web to operate each clutch.

3. In a shearing machine, having an opening, an angle shear operating adjacent said. regulator disposed adjacent said the latter comprising a single integral web suitably attached to said lower part, a plateshear shaft and an angle-shear shaft both of which are extended through said web, a gear loosely mounted on each shaft and. disposed adjacent to but not in direct engagement with one another, a common transmitter in operative engagement with each gear, a clutch on each of said shafts, means for operating each clutch, and means carried by said web to support said shafts, transmitter and clutches.

ing a lower part and an upper part, the former having an integral upward ex tensn'm and the latter comprising a single integral web suitably attached to said upward extension of the said lower part, spaced hub-bosses on said upward extension, a pair of spaced wheelbearing hubs carried by said web and provided with openings alining with openings in said hub-bosses on said upward extension, a plate-shear shaft extending through and journaling in one set of said wluxel-bearing hubs and hub-bosses, an angle-shear shaft extending through and bearing in the other wheel-bearing hub and. the other hub-bosses a gear loosely mounted on each of said shafts and disposed adjacent said respective hubformations, extension-hubs on the gears bearing in the web-hubs and having clutchfaces, a common transmitter in engagement with each loose shaft-gear, a clutch movable on each of said shafts at the outer free ends thereof and adapted for operative engagement with the clutch-faces of said gears, and means carried by said web to operate each the free end of said clutch.

for securing said pin in adcured at one end and to the machine, and at its free end carrying a vertically movable pm.

4. In combination with a shearing machine thereacross, aregulator disposed adjacent said opening and having movement in a horizontal rotary plane, and a vertically movable presser pin carried by said regulator.
